Coordinate and height accuracy

The accuracy of coordinates and heights is indicated by a series of classifications called Orders.

The following Order classification schemes are used in New Zealand:

  • Coordinate orders
  • Height orders
  • Accuracy terms and definitions
  • Changing to the new orders
  • Historic coordinate and height orders

 

In this section I roto i tēnei wāhanga

  • Accuracy terms and definitions

    To make network accuracy values easier to describe they are grouped into successive bands called Tiers.
  • Changing to the New Orders

    A new set of Orders for positions and heights was introduced to New Zealand and the Ross Sea Region in May 2010.
  • Coordinate Orders

    This page contains information on coordinate orders including the Tier and Class requirements for each.
  • Height Orders

    This page contains information on height orders including the Tier and Class requirements for each.
  • Historic Coordinate & Height Orders

    Prior to May 2010 a different set of Orders was used to describe the accuracy of NZGD2000 and RSRGD2000 coordinates and normal-orthometric heights.
  • Survey-accurate Digital Cadastre (SDC) status

    SDC status indicates the accuracy standards that the coordinates of a node comply with.
